Why it matters

Slow page response times increase bounce rates, reduce user satisfaction, and can directly harm your search rankings. Google considers page speed as a ranking factor, and slow Time to First Byte (TTFB) delays all subsequent resource loading, worsening metrics like Largest Contentful Paint (LCP). Fast response times are critical for both SEO and user retention.

Impact

Users may abandon your site before it loads, leading to lost conversions and lower engagement. Search engines may crawl fewer pages, impacting indexation and visibility. Core Web Vitals scores will suffer, potentially reducing your site's ranking in search results.

How it's detected

Slow page response times can be detected using tools like Google PageSpeed Insights, Lighthouse, Chrome DevTools (Network tab), server logs, or synthetic monitoring services. These tools report metrics such as TTFB and highlight slow server responses.

Common causes

• •Unoptimised database queries
• •No server-side caching
• •Underpowered shared hosting
• •No CDN
• •Excessive or blocking server-side processing
• •Inefficient backend code or frameworks

How to fix it

Code examples

-- Problem: Full table scan on large table
SELECT * FROM users WHERE email = 'user@example.com';

-- Fix: Add an index on the email column
CREATE INDEX idx_users_email ON users(email);
SELECT * FROM users WHERE email = 'user@example.com';

// Express.js route without caching
app.get('/product/:id', async (req, res) => {
  const product = await db.getProduct(req.params.id);
  res.json(product);
});

// Express.js route with simple in-memory caching
const cache = {};
app.get('/product/:id', async (req, res) => {
  if (cache[req.params.id]) {
    return res.json(cache[req.params.id]);
  }
  const product = await db.getProduct(req.params.id);
  cache[req.params.id] = product;
  res.json(product);
});
